I FOUNTAIN-SPITTOON.

SPECIFICATION forming part of Letters Patent No. 369,174, dated August30, 1887.

Applicatlon filed May 16, 1887.

To all whom it may concern.-

Be it known that 1, JOHN M. FLETCHER, a citizen of the United States,residing at Concord, in the county of Merrimac and State ofNewHampshire, haveinvented certain new and useful Improvements in FountainSpittoons for Dentists Use,of which the following is a specification.

This invention relates to fountain-spittoons especially adapted to theuse of dentists; and

.it consists of the various devices illustrated in the accompanyingdrawings and pointed out in the following specification and claims, ofwhich they form an inseparable part, and of which- I Figure 1 is asectional elevation of the entire machine. Fig. 2 represents a detailedsectional elevation of the urn into which a'glass for drinking may beplaced. Fig. 3 is a verticalsection of the cock used in the supplypipefor said urn. Fig. 4 is a portionof the supply-tubes, part section andpart elevation. Fig. 5 is a detached view of a portion of saidsupply-tubeshown in Fig. 4. Fig. 6 isa sec tional view showing part ofthe spittoon-bowl, its supply and drain pipes,andatrap for catching goldor other similar material. Fig. 7 is a plan View of the casting to whichthe spittoon-bowlis fitted, and Fig. 8 is a sectional view of thesupply-cock.

Similar letters indicate corresponding parts throughout.

The base may be made in one piece; but for the sake of convenience incasting it is preferably composed of the parts A A and bolted together,as shown in Fig. '1, and the part A may be screwed to the floor, ifdesired. Into the part A is fitted the hollow adjustable part B, whichis provided with annular grooves 12, for the reception of some suitablespring-stop, a, which is adapted to spring into either of said groovesor from one to another successively when said part B is-raised, but mustbe pulled or drawn out in order to lower the ceives the pipe C, aset-screw, b, being all sufficient to secure it therein.

To the upper end of this pipe C is threaded the piece D, which mightproperly be termed an elbow, into the top of which is fitted thespittoon- Serial No. 238,317. (No model.)

bowl E. This elbow D must be cored, as shown in Fig. 6,in order to carryout the purpose of my inventionviz. the passage d must be formedsubstantially as there shown, having outlets d d, leading, respectively,to the gold catcher or trap D and the drain-pipe C, when,by securing aperforated plate or screen, D, at an angle, as in Fig. 6, gold or othermaterial which it is desirable to save is dropped directly into saidtrap, the waste water only passing thence through the said screen intothe waste-pipe C. A small air-tube, F, is threaded to a central verticalhole, d formed in the top of the elbow D, connecting the waste-passage dwith the outer air, thus preventing that unpleasant gurgling sound whichis usually heard in drain-pipes having no airvent. This air-tube,however, was embraced in United States Patent No. 349,704, issued tomyself, dated the 28th day of September, 1866. Further description ofit,therefore, in this connection is unnecessary. The upper end of thehole d is enlarged, as at dfland to thisis threaded a tube surround-ingthe air-tube F, to be hereinafter described in connection with thesupply-tubesand supply passage d in said elbow D.

7 From the top of the adjustable extension B extends vertically a tube,C, carrying at its top an urn, E, which is provided with a perforatedplate, 6, upon which to place an ordinary drinking-tumbler. At someconvenient place upon this urn is secured a cock controlling the supply,to be hereinafter described. The adaptation of suitable supply-pipes tomy improved fountain-spittoon involves the use of telescoping tubes inorder to use nothing but metal pipes throughout.

Within the larger part of the base A is located a cock, G, connectingthe pipes H H. This cook, it will be seen by reference to Fig. 8, may beturned, as at G, so as to entirely out off the supply, or so as to admitthe water to the pipe H and thence to the spittoon bowl or urn; or itmay be turned so as to cut off the supply to said pipe H and allow it torun off into the waste by means of the outletorifice gi. e., when thearm g islying horizontal on one side, the supply is cut off; when it isplaced vertical, the supply is permitted to enter the pipe H and itsconnections, and when said arm is placed horizontal in a positionopposite to the position first named the supply is kept freelycirculating through the orifice 9 into the waste, and hence any dangerfrom freezing is avoided. This arm 9 maybe readily moved by the foot ofthe operator. The stem leading from said arm to the cock may be casil ypacked to prevent leakage through the base A.

The tube H is provided with one or more annular grooves, h, in which toinsert packing. I, in order that the said tube may be perfectly tightwithin the outer or telescoping tube, J, connected by the union K to thebranch and extension tubes, respectively, J J". The branch J passesthrough the wastetube C, and is threaded to the supply-passage d in theelbow D, which connects with or opens into the enlarged portion d of thehole (1, as seen in Figs. 6 and 7, thus throwing the water in acylindrical column upward through the tube f against the cap or buttonF, which may be threaded to the top end of the air-tube F and serve as asprayer for supplying the water on all sides of the spittoon-bowl atonce. By setting down the said button nearer to the upper end of thetubef'the spray may be made finer, and vice versa.

The cock L is provided in its lower part with three passages-viz., Z Z Zall of which connect with the valve L, which has three ways, as seen inFig. 3. The pipe J 2 connects with the passage Z, which passes centrallyfrom near the bottom of the cock L to its top, where a tube, M, isattached. This may be bent, as seen in Fig. 1, so as to throw water intoa tumbler, and above the three way valve L the said passage Z isprovided with a valve, L, for cutting 01f the supply of water to thebent pipe M. To the passage Z is connected a short tube, N, having itsfree end bent upward through the perforated plate 0. To this is attacheda flexible tube, it, having at its outer end a suitable tip, 0, forthrowing a small stream of water into the mouth of a patient; or aninjector may be used upon this tube. To the passage Z a short tube, N,is connected. This runs down part way into the waste-tube O, and aboutthree inches (more or less) from the said cock L. This tube N isprovided with a branch, a, as seen in Fig. 2, which, like the tube N, isbent upward through the plate c, and to which is attached a flexibletube, N, for drawing the saliva from the mouth of a patient. If desired,a tip, 0, as seen in Fig. 1, may be attached to the free end of saidtube to be used as an ejector, and an injector, 0, may be used, uponwhich is provided a stop-valve, so that, even though the valve L beplaced in the position shown in Fig. 3, no water shall be permitted toescape from the injector. This would also be desirable on account of thepassage Z which would then get the benefit of the full force of thesupply, the principle of the ejector being that of suction-to wit, whenthe valve L is turned, as indicated in Fig. 3, the supply passes fromthe passage Z into the said valve and thence into either of the passagesZ Z". The passage of said water dowuward through the tube N creates asuction in the branch tube a, and immediately acts as a siphon-pump inthe flexible tube N;

A simple and elfeetive means for connecting the base and the supply-tubeII with the lead or other pipes within the floor of a building is shownin Fig. 1. The tube H is passed up through a telescoping tube, P, whichis rigidly secured to an inside collar, p, at the bottom of thewaste-pipe P. The lower end of said tube I-I may be connected by a wipedjoint to a lead pipe, It, and after the base of the machine is set inplace the upper end of said tube H may be then threaded to the cock G,as previously stated.

The wastepipe P may be provided with a boss, 1), on its side, to whichis threaded a short pipe, 12 by which the waste is conducted to theleaden wastc-pipe ll, which may also be attached to the pipe 1;" by awipe-joint, as in Fi l.

Ly telescoping the tubes Ill J and forming the parts A B verticallyadjustable and capable of rotary movement one within the other thespittooirbowl E and the urn E may be elevated or lowered and revolved atwill without the necessity of using flexible supply and waste pipes,from which there is constantly more or less danger of leakage.

Having described my improvements, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a icuntain-spittoon, the combination of telescoping supply-tubesand telescoping standards through which the waste is passed, formed intwo or more parts capable of vertical adjustment and rotative one withinthe other, substantially for the purpose set forth.

2. In a fountain-spittoon, the combination, with the spittoon-bowl andits supporting-arm, of an iuterposing section connecting the two,provided with supply and waste passages, as shown, and a cup attachedthereto and connected with said waste passage for catching the particlesofgold and other filling materials, and means whereby everything passingfrom said spittoon-bowl must first enter said cup before passing intothe waste-pipe, substantially as described.

3. In a fountain spittoon, the combination of the tumbler rest or urn, aperforated plate or grate, a suitable standard cored substantially asshown and connecting the supplypipe, the pipes carrying an injector andan ejector, a pipe or faucet for supplying drinking-water, and thenecessary valves operating, in connection with the cored passages,within said standard, substantially as set forth.

4. Telescoping supply-tubes within telescoping standards, adapted forcarrying off the waste, the interior tube being provided with annularserrations, and the exterior tube having a spring-catch for engagingsaid serrations, all combined and arranged in a fountain-spittoon,substantially for the purpose explained.

5. In a fountain-spittoon, the combination IIO of a base and standardprovided with a passage for waste water, a spittoon-bowl, a supply-pipe,and a three-way cock adapted to admit Water'to pipe leading to saidbowl, to admit water directly to said waste-passage, and to shut thewater from either or both said outlets, all constructed and operating inthe manner and for the purpose herein described.

6. In a fountain-spittoon, the combination of a base or standardprovided with a passage for waste water, a spittoon-bowl, a supplypipe,a three-way cock adapted to admit water to pipe leading to said bowl, toadmit water directly to said'waste-passage, to shut the water fromeither or both said outlets, and means I 5 for connecting saidsupply-pipe and waste-passage with their respective pipes underneath thefloor, all substantially as and for the purpose set forth.

In testimony whereof I affix my signature in 20 presence of twowitnesses.
